"Wrong." Niu Zihao exclaimed. However, this was also expected by him.

The answer is x∈ [0,9].

Sure enough, this Xueba system is unreliable, how can such a good system be attached to himself, if he doesn't have a scumbag system, it's very good. Niu Zihao looked very sad, and it was really uncomfortable to be deceived. A pie in the sky must be a trap.

Just when Niu Zihao felt disheartened, an electronic screen suddenly appeared in front of his eyes, probably the size of a TV. Niu Zihao was stunned, and saw that it said:

Host Niu ZihaoPlease note that the school master system has just been installed. Your level is temporarily level 0, if you want to upgrade, check the upgrade method column.

Niu Zihao thought about it and clicked on the "Upgrade Method" column.

The interface suddenly changed, and the host could only unlock level 1 by reading the book carefully for 8 hours in a row, do you want to confirm it?

Without thinking about it, Niu Zihao pressed confirm. I saw a countdown interface appear in front of me, 08:00:00. The timing system has been successfully activated by the host, please complete the task within the specified time to unlock Level 1. If it is not unlocked within the time limit, the Xueba system will automatically crash, and the host's IQ will be reduced by 20%.

Niu Zihao, who has always been very calm, is really panicked now. He is actually not interested in unlocking the next level, but if he doesn't complete the task, he will reduce his IQ by another 20%, and it is estimated that he will be reduced.

For a while, Niu Zihao's head was full of paste. This late self-study, where to read so many books. When I was meditating, I found a suitable place. This system was brought from the library, and I went to the library to read books.

Watching Niu Zihao rush out of the classroom, Zhao Liyang sighed, sure enough, it was three minutes of heat, and he went to the toilet to fool around again.

When he came to the door of the library, Niu Zihao didn't have the key here, so he couldn't open the door at all, what should I do. Seeing that more than ten minutes had passed since the countdown, Niu Zihao began to get nervous.

Staying up late tonight, Niu Zihao was able to hold on, no problem at all. In the past, the Internet café was full of nights, which was enough to prepare him for "fighting all night". But the question is, how do you get into the library?

There are always more solutions than difficulties.

He began to peek around the perimeter of the library, trying to find a way to get inside.

Walk around the administration building to the windows of the entire floor, then jump down two floors and into the ventilation vent above the library so you can get inside.

Niu Zihao shook his head, feeling that it was not very realistic. This is how you want to get into the library, unless it's Spider-Man. It can spin silk and form nets.

"Huh?"

Windows, yes, windows.

Niu Zihao had a whim, and inspiration came in an instant. Access is only possible through the window on the side of the library. He was also impressed by his ingenuity when he could think of such a solution.

But when he got under the window, he was in trouble again. The windows are so high that you can't even reach them, so how can you get in?

Niu Zihao looked around, but there was a trash can that caught his eye. Standing on the trash can, you can't go in.

He worked hard to bring the trash can, and he didn't care about the garbage in his hand. Standing on the trash can, one palm broke the glass on the window. "Bang la la", the sound of glass breaking, and this quiet and peaceful night, seems a little out of place. Niu Zihao doesn't care about deliberately damaging school facilities, in front of the Xueba system, those are insignificant, or even negligible.

In a natural free-fall movement, he entered the inside of the library.

"Tonight, I'm going to spend the night in the library." Niu Zihao said.

He turned on the library light, picked up a book and started reading.

Countdown to 07:33:56.

At all, no matter what kind of literary classics or popular science publications, Niu Zihao picked them up and read them.

Quest completion: 12%, the host has read 7 books. Please keep up the good work and keep up the good work. The approximate time to complete the mission is 5 a.m.

Listening to the sound of the countdown echoing in his ears, Niu Zihao looked at every book in his hand seriously, for fear that if he stopped for a second, the progress bar would suddenly stop.

Mission completion: 37%.

Mission completion: 53%.

Mission completion: 89%.

Niu Zihao has never been so excited to read a book, the more he reads, the more he feels, just two hours have passed, he has read almost all the books on a horizontal shelf.

……

On such a lonely and lonely night, only Niu Zihao was left alone to read in the library at night. If this is discovered by his homeroom teacher, he will not be moved to cry.

Mission Completion: 99%......

It's close, it's close.

He quickly flipped through the pages in his hand, admired the beauty of the words emanating from between the lines, savored the classic stories, and couldn't extricate himself from the world of literature. Reading a book is like making a friend with an ancient sage, and he also hopes to sing about wine with his friends and sigh at the geometry of life. The kind of flavor brought by reading books made Niu Zihao fall into it.

By the time he reached the last page, closed the book, and placed it on the shelf, the task was complete.

In front of him, the electronic screen just now was displayed.

A mechanized voice sounded:

"The system has detected that the host has successfully completed the mission, unlocking Level 1."

Xueba System Lv1: Never forget

"Wow, is there such a cool operation?" Niu Zihao couldn't help but sigh.

In order to continue to verify the upgraded system, he took the book "Dream of Red Mansions" from the bookshelf and turned a page casually.

After a while, Niu Zihao finished reading it, and now he has to recite it to see if he really can't forget it.

I don't want to be unlucky, and I am also dyed in this wind in the Qiong Boudoir Embroidery Pavilion, which is really negative to the virtue of Zhong Lingyuxiu! Therefore, the ancients burned all but the four books. And when the people saw that he was so mad, they did not say these serious things to him. Lin Daiyu is the only one who has never persuaded him to become famous since he was a child, so he respects Daiyu deeply.

Just the short paragraph he had just recited was enough to make Niu Zihao feel very surprised. Don't say a short paragraph, with this Xueba system, even if it is punctuation, which word is on the page and how many lines, he can say it accurately. Even if it is a book of "Dream of Red Mansions", Niu Zihao reads it once and reverses it backwards, which is more than enough.

Such a good academic system, why don't you run to others, but you only recognize yourself, is it because of your scum, or is there another reason?

One question after another flashed quickly in Niu Zihao's brain, and Niu Zihao no longer considered these. The most important thing now is that you have the ability to remember and learn.

There is a golden house in the book, and there is Yan Ruyu in the book.

Niu Zihao picked up "Yan Ruyu" and began to study seriously.
